And effects also depend on the seal material, etc.

Nothing you add will fix a worn out seal though. It took care of a noticeable trans input shaft or pump seal leak on the Jeep and the leak has never returned. I've personally seen AT-205 reseal bring some life back to seals that weren't sealing well due to being old and hard. So it works for cleaning anything that needs one of those.Ĭoolant stop leak additives are all pretty much a no-go due to side effects. Although if the system isn't dirty, they aren't going to do anything.īerryman B12 is at least a pretty decent carb cleaner / solvent.

Ever since Derek the owner of Vice Grip Garage drug this car out of its. Techron, Regane, and other fuel system cleaners containing PEA definitely do clean things. DOES IT GET BETTER THAN AN ABANDONED 72 CHEVELLE + BOOST spoiler alert, it doesnt. It makes good cutting oil too, as it smells nice. There's definite evidence that a bit of Marvel Mystery Oil added to engine oil can dissolve some varnish, sludge, etc. But if you know why you're using an additive and what it's intended to do, some of them can help. There are definitely additives out there that are useful, but typically only for fairly specific purposes. In reality, sometimes it's just copper chewing gum Reading the label, you would think it cures hydrophobia, the vapors, baldness, and restores your engine to better than new. You really have to know what the product does instead of just reading the label. Too many times I see people (for example) using some oil additive to stop a cam tick and it starved the bearings when all they needed was a valve adjustment, or using stop leak because they saw coolant on their driveway when all it needed was the hose clamp tightened a bit. Not unlike giving a dying person some morphine so they're at least not screaming when they die. Marvel mystery oil is mostly just a very viscous oil that increases the existing oil's viscosity to mask problems and give a dying engine a little peace before it spins a bearing or seizes a pin. I've taken a tire to a shop for a plug and they refused because someone put slime in the tire. Many of the fix-in-a-can are just band-aids if used incorrectly. So, a water pump, radiator, two heater cores, intake gaskets, $500 and a wasted week waiting for parts later, I was able to fix a $50 problem. Their solution was a can of stop-leak in the radiator so they could kick the can down the road to me. Previous owner of my Branger had the common intake leak.
